The relay is fully configurable with the aid of front-end software or a man machine interface unit (MMI). Event records can also be down loaded via the MMI (iRDA -infra red link) for further analysis. All the settings are password protected. The relay has an on board database where time and date stamped event and fault records are kept. The event records are read only while the fault records are granted full access rights. The front-end is also equipped with a data recorder which could be used to monitor motor performance.
